Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Up to 10,000 IU daily per 2.2 lbs (1 kg) body weight or 500 to 1,000 lipase units per gram of fat consumed in the diet
People with cystic fibrosis tend to have insufficient pancreas function. Supplementing with pancreatic enzymes will often lead to improved digestion, especially of fats.
People with CF tend to have insufficient pancreas function. Supplementation with pancreatic enzymes will often lead to improved digestion, especially of fats. The current recommendation for people with cystic fibrosis is to supplement with pancreatic enzymes at meals. Amounts should not exceed 10,000 IU of lipase per day per 2.2 pounds body weight1 or 500 to 1,000 lipase units per gram of dietary fat consumed,2 as larger amounts may damage the large intestine. A double-blind trial found enteric-coated microsphere enzyme preparations to be superior to enteric-coated capsules for reduction of abdominal pain and improvement of digestion.3Because pancreatin is rapidly emptied from the stomach during digestion, people taking these enzymes may obtain better results by spreading supplementation throughout the meal.4

Lipase may be beneficial for people who do not produce adequate digestive secretions from the pancreas, a common occurrence with celiac disease.
People with celiac disease often do not produce adequate digestive secretions from the pancreas, including lipase enzymes5 In a double-blind trial, children with celiac disease who received a pancreatic enzyme supplement along with a gluten-free diet gained significantly more weight in the first month than those treated with only a gluten-free diet.6 However, this benefit disappeared in the second month, suggesting enzyme supplements may only be useful at the beginning of dietary treatment.

People with Crohn’s disease may be deficient in lipase. Supplementing with enzymes might improve the malabsorption that is associated with the disease.
People with Crohn’s disease may be deficient in pancreatic enzymes, including lipase.7 In theory, supplementing with enzymes might improve the nutrient malabsorption that is often associated with Crohn’s disease. However, people with Crohn’s disease considering supplementation with enzymes should consult a doctor.
Products that contain lipase also usually contain other enzymes that help digest carbohydrates and protein. In the U.S., pancreatin, which contains lipase, amylase, and proteases, is rated against a government standard. For example, “9X pancreatin” is nine times stronger than the government standard. Each “X” contains 25 USP units of amylase, 2 USP units of lipase, and 25 USP units of proteolytic enzymes. Taking 1.5 grams of 9X pancreatin (or a higher amount at lower potencies) with each meal can help people with pancreatic insufficiency digest food.
Most of the body’s lipase is manufactured in the pancreas, although some of it is secreted in the saliva, as well. Pancreatin contains lipase along with two other groups of enzymes: proteases and amylase.
